Fig. 13 is a vertical section of a modification ofthe rotary lifting member, and Fig. 14 is a similar view of anothermodification of the same.

In all the above views corresponding parts are represented by the samecharacters of reference. y

The phonograph is provided with the usual bed-plate 1,011 `which ismounted in suitable bearings (not shown) the main shaft 2, which carriesthe usual mandrel and which for a part of its length is cut with a finescrewthread to feed the reproducer len thwise of the record. The usualstationary ack rod 3 is shown, upon which is mounted the usual sleeve 4,arranged to slide onsaid rod and carry the reproducing device. (Notshown.) This sleeve, together with the parts usually attached theretofor sup orting the reprodueei, 11111)' be termed t traveling carriage."Secured to the sleeve 4 is the usual x spring-:11111 5, which carriesthe feed nut or nuts 6 for engaging the threaded portion of the mainshalt 2, and thereby im arting a progressi ve forward movement to t etraveling carriage, as is common in this art.

In applying my improved re eating attachment to a phonograph I nia e uscof a small compact base 7, which by means of screws S engaging slots 9is removably and adjustably secured to the bed-plate 1. The base 7 isprovided with two bearings l0 10, in which is mounted a return-shaft 11,having a coarse-pitch return-screw 12. 'lhc returnshaft 1 1 may bedriven from the main shaft 2 by any approved gearing, preferably two iurgears 13 13, mounted on the two s afts, respectively, and in engagementwith each other, as shown. 4 by a split collar 14 is an arni l5, havinga bend at its center, so that it projects over in front of andsubstantially in line with the spring-arm 5. The arm 15 is provided witha contact member of peculiar construction, which is adapted to bcengaged by a pin or projection rotating with the return-shaft 1l andlifted and brought into enga ement with the return-screw 12, whereby t efeed-nut will be disengaged from the feed-screw and the travelingcarriage will be rapidly returned to its initial or starting position.This member in its preferred form is a dog 16,

Secured to the sleeve pivotally connected to the forward end of the arm15, so that it is capable of oscillation in two planes-one longitudinaland one transverse with respect to the axis of said returnscrewshaft-that is, the axis of thc first oscillation is perpendicular to thereturn-screw axis and the axis of the second oscillation is parallel tothe return-screw axis. The range of movement on the first axis is sli htand is limited for reasons which will e subsequently pointed out. Theseaxes of oscillation are prefcrabl secured by forming the dog with a airo upwardly-projecting ears 17 and 1'8, ig. 6, provided with openings 19and 20, respectively, through which passes a pin 21,-ri id with the arm15. Bhe opening 19 is slight y greater in diameter than the pin 2l andthe openin 20isconsiderabl greater Furt ermore,-

in diameter thant esaid pin. the distance between the earsV 17 and' 18is considerably greater than the width of the` arm 15. The result isthat thedog 16 may oscillate freely upon the pin 21' as an axis, and byreason of the large opening 20 and the looseness of the pin in the oening 19 the dog may swing through a smalliangle upon a fore-and-aftaxis-that is, one which is perpendicular to the plane of the aper u onwhich Fi 6 is drawn and which is locate at or near t e left end of thein 20. The` dog 16 is rovided with a shoulder 22,extending entire yacross the same, the metal above said shoulder being cut away. A rib 23and a tail 24 project downward from the d'og 16. The rib 3 is adapted toen age the thread of the return-screw l2 and e ect the return of thetraveling carriage, and the tail 24 is so located as to contact with aninclined rod 25, adjustably held by a set-screw 27 in a boss 26,` whichprojects from the plate 7 to effect the lowering of the carriage. Theelevation of the traveling carriage is effected by a rotary projection,which is preferably carried by the return-screw shaft. In its preferredforni a disk 28 is mounted on said shaft and may be adjusted along thethread of the screw and held by a set-screw 28, which presses against ablock 43, occupying a groove in the bore oi" the disk and having a rib43, which engages the thread of the screw. The disk 28 carries a pin 29,which projects toward the dog 16.

The oeration of the device is as follows: When t e phonograph-re reduceris in its operative position, the fee( -nut 6 engages the feed-screw 2and imparts a progressive forward movement to the traveling carria e.During this time the dog 16 hangs u on t e pin 20, as shown in Fig. 3.The forwar movement of the carriage causes the do 16 to approach theliftingin 29 until the s oulder 22 intersects the pat of the rotatingpin 29. As soon as the pin reaches that portion of its path intersectedbythe shoulder 224 it contacts with the same, and the extent of overlap`viens, however, that suo'h oscillations? the dog 16 will increase theoverlap of the shoulder 22 with respect. to the pin 29, sinne path ofthe shoulder is along the arc a t of Fig. 6.

paretivelv Wide @verle of the contcting surfaces has beenpbtained, andthe 'The dog 16 enti Verin l5' Operation begins. i ere lifted hy theengagement ei' the with the shoulder 22, and b reason of the weight ofthe carriage smily frictionel en=- agement of the parts the pin 29carries the og 1B forward until its lower snrfeee rests upon 1thereturn-screw l2, as shown in Fig, 4. As scones the screw revolves intotheproper position the drops into engagement with the thread of thescrew, and thereby senses the sound-box carrier to be moved toward itsinitial position. As soon es the tail 24 reaches the inclined rod 25 thedog 15 is thrown from engagement with the returnscrew, and the carriagefallsinto its operative position, with the feed-nut 6 in engagement withthc feed-screw. The operations dcsorihed may then be reeet-erlindeinitely.

it should be noted t at the thread of the return-screw pressing againstthe rib 23 of the flog 16 tends to turn the dog on its foreand-ait axis;but since the range of such movement is lilnitefl the rib 23 willrenisin in engagement with the thread of the screw and the carriage willhe moved along by the scifi screw. By reason of the motel above theshoulder 22 being cut away it is impossible for the fece of the flog 16to De carried egeinst the enil ei the pin 29 to thereby reusertlieVparts to juni and stop the machine. Y

The device of Fig. is similar in all resnetsY to the structureheretofore described, ezinept that the dog 16 connected to the erm 15 byIneens of a pin 2U, rigid with the ears 17 enfl i8 and journaled in aconical hearing 311' formed in the arm 15, said bearing permitting elimited oscillation of the pin 2(1therein on e fore-endeft exis situatedneer the left-henri end of the pin and per endieuler te the plane of thepeper upon W drawn.

In the device of Figs. 8, 9, enrliilfthe 'deg' 16 is pivotelly connectedto "eetengiilar block 31 hy Ineens of e pivot-pin 32. The bloei; 3l ispivot-elly connected te the'erin 15 by trunliions 33, which turn in lugs34, de-

pending from the enti Vol the erin l5. The

oscillation of the block 31 upon its trunnions 33 is limit-eil by theenvegement of the block 33 Vith the ilnder surface of the erm 15. es

At the end of this movement e, een?Y 'i 'eh Fig. 7 is,V

position,v of a rotary lifting member, and e 'esse is not capable ofoscillation on a forennd-aft exis. The increase of overig is ob-steinehowever, by substituting ier t e eenflfLft-shoulder 22 of the degi6 e pewl 36, piv oteil' toears 37', interel with the dog i6', hy apivot-*pin 38. It should he noted that that ege e'theipawl 36 which willhe nearest the YYlifting-pin 29 is not situated tiirectl f below thecenter of theA pin 3S, 'but is located considernhly in eclvenee thereof.Therefore the en ragement of the pin 29 with the pawl 36 will turn theseine on its pivot 38 until the ulpper end of the avi-*l abuts againstthe sideA (l the :log l5, t erehy preventing further pivotal inetien.rihe llftingin 29 will thereupon litrthe rlogl end wil de osit the semeupon the ret'urn-serew -1 2, there Weensine the return movement of theparts to take place.

It is obvious that insteerli'oi Vpivoting the oonteeterleg Lf of thetraveling carriage en two axes it rfisy'he pivoted one single erallei tothe return-screw, es the flog lf' 'oi j ign 1,end the increase ofoverlap ohtnineil hy'pivotini? tlie'lii'ting pro'cetion on en exisperpendieuer to the axis o the return-screw es in Figs. 13 and 14.

ln Fig. i3 the disk 2S', which carries the lifting-pin 29", is pivoteilto a sleeve i1G hy pins or trunnions 4l, the exis oi' which isperpendicular to the exis oi' the returneerew 12.

The pin 2Q isprovided with e. sloping surface 44, which is nils-pfeil to ooo lerntewith e similar surface 451, nrrner on t e shoulder 22 of the dog 16, endthereby turn tlie disk er ring upon its trunnions 4l, thereby increasingthe overlap ei the pin 29 with respect te the shoulder 22'.

ln the device of Fig. 14 the liitin member comprises e disk '282,provided witi s,V vpsvl i5, setin the body thereofj and piveted on enaxis 46, which is erpendieular to the axis of the screw 12. T e pee-I isnormally held in the pesitionshown by e. spring 17, secured to the eseresY 4S. (lbviously the pewV i5 upon striking the shoulder 22 of thedog i6, carried' by; the arm 15, will be turned on its pivot 46, t'erehv increasing the overlap of the contesting parte.
